a fatty material, made up of glial cells, that insulates the axon and allows for the rapid movement of electrical impulses along the axon
Myelin sheath
250
the basic unit of the nervous system; it operates through electrical impulses, which communicate with other neurons through chemical signals; they receive, integrate, and transmit info in the nervous sys.
Neuron
251
a chemical substance that carries signals from one neuron to another
Neurotransmitter
252
small gaps of exposed axon, between the segments of myelin sheath, where action potentials are transmitted
Nodes of Ranvier
253
the neurotransmitter involved in states of arousal and awareness
Norepinephrine
254
a region of the cerebral cortex, at the back of the brain, important for vision
Occipital lobe
255
a division of the ANS; it returns the body to resting state
Parasympathetic division of ANS
256
a region of the cerebral cortex, in front of the occipital lobes and behind the frontal lobes, important for the sense of touch and of the spatial layout of an environment
Parietal lobe
257
a neurological disorder that seems to be caused by dopamine depletion, marked by muscular rigidity, tremors, and difficulty initiating voluntary action
Parkinson's disease
258
all nerve cells in the body that are not part of the CNS; somatic and autonomic
Peripheral nervous system (PNS)
259
observable physical characteristics that result from both genetic and environmental influences
Phenotype
260
located at the base of the hypothalamus; the gland that sends hormonal signals controlling the release of hormones from endocrine glands
Pituitary gland
261
a property of the brain that allows it to change as a result of experience, drugs, or injury
Plasticity
262
a region of the frontal lobes, especially prominent in humans, important for attention, working memory, decision making, appropriate social behavior, and personality
Prefrontal cortex
263
in neurons, specialized protein molecules, on the postsynaptic membrane, that neurotransmitters bind to after passing across the synaptic cleft
Receptors
264
a gene that is expressed only when it is matched with a similar gene from the other parent
Recessive gene
265
the electrical charge of a neuron when it is inactive
Resting membrane potential
266
the process whereby a neurotrasmitter is taken back into the presynaptic terminal buttons, thereby stopping its activity
Reuptake
267
one of the three types of neurons, these afferent neurons detect information from the physical world and pass that info along to the brain
Sensory neurons
268
a monoamine neurotransmitter important for a wide range of psychological activity, including emotional states, impulse control, and dreaming
Serotonin
269
a major component of the peripheral nervous system; transmits sensory signals to the CNS via nerves
Somatic nervous system
270
a neurotransmitter involved in pain reception
Substance P
271
a division of the ANS; prepares the body for action
Sympathetic division of ANS
272
the site for chemical communication between neurons, which contains extracellular fluid
Synapse, or synaptic cleft
273
neurological condition in which stimulation of one sensory or cognitive pathway leads to automatic, involuntary experiences in a second sensory or cognitive pathway
Synethesia
274
the lower region of the cerebral cortex, important for processing auditory info and memory
Temporal lobes
275
small nodules, at the ends of axons, that release chemical signals from the neuron to the synapse
Terminal buttons
276
the gateway to the brain; it receives almost all incoming sensory info before that info reaches the cortex
Thalamus
